Important advices for installation
1. Bansbach gas springs will oper- ate in surrounding temperatures from -30°C to +80°C. We can equip our springs with special seals to withstand temperatures as low as The facts mentioned here, are routine for a lot of our regular customers. -55°C or as high as +200°C. For applications in low tem- perature surroundings, a detailed clarification of the requirements is necessary. The surrounding temperature has influence on the gas spring cha- racteristic. Changes of the exten- sion force as well as of the damp- ing characteristics have to be considered and should be tested in advance within the application. Gas springs should not be over- heated or put in open fire! Other environmental conditions can also influence the considerable lifetime of gas springs. Please take appro- priate, preventive measures into consideration. 2. Gas springs are filled with pure nitrogen. Nitrogen is an inert gas, which does not burn, will not explode and is not poisonous. The use of easylift gas springs requires the knowledge and attention of some data and facts as do other technical systems which have to do with force development. You can see the substantial criterions on this page. Our consultants will of course explain in detail all technical facts which are important for your application.
influences) we refuse the liability for damages which result from this fact. Warranties aren’t possible anymore. 5. Bansbach gas springs can be used generally as a limit stop in both directions. The occurring forces should not exceed the fol- lowing approximate values.
and use suitable connecting parts. 8. If gas springs are damaged visibly (broken or deformed connecting parts, bended piston rod, dented cylinder) due to exter- nal cause (accident, collision, extreme overloading,...) the pres- sure has to be released before the gas spring is being dismantled or used. Please note our disposal and recycling instructions! 9. Gas springs are maintenance- free. Do not grease or oil the pis- ton rod. 10. The piston rod must not be painted and should be protected against shocks, scratches and dirt as well as against aggressive and corrosive media. The cylinder should not be deformed. Any such damage will destroy the sealing system. 11. Bansbach gas springs can be stored in any position. Significant pressure loss due to long storage is generally not to be expected. (If necessary, please ask for our storage instructions.) However, sticking effects can occur, which require an increased expenditure of force when operated for the first time (initial break-away force). 12. Warranty claims expire latest 1 year from date of production. Manufacturing mistakes and/or quality defects are immediately noticeable. If you are unhappy for any reason with the delivered quality, we ask you to return the springs immediately. Your com- plaint and a copy of the original invoice must be enclosed. 13. If gas springs are sent to us for a detailed examination, the agree- ment for the demolition of this part is given and the property right expires. A return delivery of single components is not possible. If applicable please assign the delivery with e.g.: “For functional testing and please return the parts back”. Is no objection available, the delivered gas springs will be disposed 1 week after the announcement of the test result. Basically applies: For unjustified claims we reserve the right to charge a lump-sum or the actual costs incurred for handling and disposal.
14. Bansbach gas springs - which mostly consist of parts held in stock - are produced due to customer’s orders. A cancellation, modification afterwards, change or refusal is therefore not possible. 15. Bansbach gas springs are built and tested for highest requirements and highest reli- ability. Installation advices as well as our comprehensive advice will help you in choosing your gas springs.

The examination of the suitability for the respective application has to be executed by the customer! You aren’t allowed to use products that are unsuitable and faulty or for the applica- tion. Bansbach gas springs and dampers are wear and tear products. We exclude any lia- bility for the functionality and life-time of your end product. If a failure of our product can lead to personal injury and/or damage to property, additional safety measures must be taken. 16. The gas spring accessories (such as releases systems for lockable gas springs) have been developed and matched to Bansbach gas springs. A func- tion with third-party products cannot be guaranteed. 17. Damping characteristics can create vibrations which lead to a resonator within the applica- tion and may cause noise. Little changes concerning the installation or the attachments may help to avoid them. 18.You can select your best dimensions yourself, within the mentioned limits. The toler- ance for the lengths is gener- ally deemed to be ± 2,5 mm; in series production, there is a tolerance of max. ±1mm. If very high demands are placed on durability and stability, please avoid the combination of small diameter + long stroke + high force.

This isn’t valid for lockable gas springs and traction springs!
Attention: The figures refer to the average pressure range of the respective size. Some connectors such as elbow joints may not be suitable for the above values. In case of high limit stop forces as well as for permanent load, we recommend an additional mechan- ical limit stop. In case of reaching the limit range or a permanent use as limit stop please contact Bansbach easylift. 6. Gas springs should be installed with the piston rod downwards. This position ensures the best damping effect. Only Bansbach gas springs include an integrated grease chamber which allows different directions of installation. 7. Gas springs should not be exposed to any tilting or sideforces during operation. If this is unavoid able, please check the installation
But:
Gas springs have very high inter- nal pressure (up to approx. 300 bar). Do not open without instruc- tion!
3. Disposal/Recycling: Gas springs consist mostly of metal and can be recycled, but first the gas spring must be pressureless. 4. All gas springs are labelled with the warning „Do not open, high pressure“, the part number and the production date. If these dates are unreadable (removed, painting of the gas springs or any other
